I've been overhauling check.rdfa.info over the last few days.
check.rdfa.info parses a page for RDFa, displays it in a reasonably
readable manner, and points out any obvious errors in your data.
Major changes:
- Caught up with latest RDFa 1.1 editors' drafts (in fact, possibly
ahead of the editors' drafts in some respects).
- Covers the newly revised Open Graph Protocol, and performs a lot
more linting for OGP.
- Covers the schema.org in RDFa, though currently there are very few
warnings, etc generated.
